【问题描述】：

我想从标点符号和连词中清除用户输入的字符串。连词存储在file.txt (Stop Word.txt)中

我已经尝试过这段代码：

f = open("Stop Word.txt", "r")

def message(userInput):
    punctuation = "!@#$%^&*()_+<>?:.,;/"
    words = userInput.lower().split()
    conjunction = f.read().split("\n")
    for char in words:
        punc = char.strip(punctuation)
        if punc in conjunction:
            words.remove(punc)
            print(words)

message(input("Pesan: "))

输出

when i input "Hello, how are you? and where are you?" 
i expect the output is [hello,how,are,you,where,are,you]
but the output is [hello,how,are,you?,where,are,you?]
or [hello,how,are,you?,and,where,are,you?]

【解决方案1】：

使用列表理解来构造单词并检查单词是否在您的连词列表中：

f = open("Stop Word.txt", "r")

def message(userInput):
    punctuation = "!@#$%^&*()_+<>?:.,;/"
    words = userInput.lower().split()
    conjunction = f.read().split("\n")
    return [char.strip(punctuation) for char in words if char not in conjunction]

print (message("Hello, how are you? and where are you?"))

#['hello', 'how', 'are', 'you', 'where', 'are', 'you']
